Ok so what is do is
the bottom half is the radius
the top half is a little bit m ore tricky
we can do
18=base
15=sides
makes an equilateral traignel
split it up into
base 18/2=9
hypotonuse 15
height=?
9^2+x^2=15^2
81+x^2=225
x^2=144
x=12
height=12
add
radis=15
height=12
15+12=27
27 cm
Radius of the circle = 7 in.
The area of the circle.
A. 154 inches squared. ✅
We know that,
Answer: The point estimate for the mean weight of all spawning Chinook salmon in the Columbia River is the mean weight from your sample = 31.2 pounds .
Step-by-step explanation:
The weights of spawning Chinook salmon in the Columbia river are normally distributed.
Given : The mean weight from your sample is 31.2 pounds with a standard deviation of 4.4 pounds.
The point estimate for the mean weight of all spawning Chinook salmon in the Columbia River is the mean weight from your sample i.e. is 31.2 pounds because the best point estimate for population mean is the sample mean. [in normal distribution]
The anwser is 610
you would add the emails sent on Monday and Tuesday which equal 690 and subtract that by the total humber of emails which is 1300
1300-690=610
divide the 2m by 9 then the -5 by 9
giving 2m/9 - 5/9
